Observation of self-organized square lattice pattern formation in surface barrier discharge plasma

Study on the D<sub>2h</sub> superlattice pattern in dielectric barrier discharge

“…介质阻挡放电系统由于其装置简单易于操作 且产生的斑图种类多样而成为倍受关注的非线性斑图 的形成系统 [10][11][12] . 在介质阻挡放电系统中通过普通水 电极作为放电电极观察到的斑图种类很多, 其中包括 圆环斑图 [9,13] 、D 4h (含有对称操作E, 5C 2 , C 4 , C , i, σ h 和4σ i , 称为D 4h 点群)对称性的四边形超点阵斑 图 [14,15] 和D 6h (含有对称操作E, 7C 2 , C 6 , C 3 , C , i, σ h 和6σ i , 称为D 6h 点群)对称性的六边形超 点阵斑图 [16][17][18] . 例如 Sánchez-Álvarez等人 [19] 观察到一 个四边形斑图, 其由D 4h 对称性的点阵构成; Dong等 人 [20] 观察到一个D 4h 四边形发光斑图, 其由两种D 4h 对 称性的子点阵耦合而形成; Dong等人 [21] 观察到一个3 层耦合斑图, 其由3种D 6h 对称性的六边形子点阵嵌套 引用格式: 韩蓉, 董丽芳, 黄加玉, 等.…”

Formation and characteristics of patterns in atmospheric-pressure radio-frequency dielectric barrier discharge plasma

“…[7][8][9] To date, major works have even been carried out on pattern formation and pattern resolution using plasma supplied by a power source at a frequency on the kHz order. [10][11][12][13] Detailed investigations were focused on the relationships of the pattern configuration with the applied voltage, 14) the power frequency used for pattern formation, 15,16) the gas and pressure used, 17) the barrier capacitance and dielectric constants applied to control the discharge structure, 18) and the variations of the self-organized structure in microgap barrier discharge. 19) Regarding plasmas generated at atmospheric pressure employing a RF power source such as 13.56 MHz RF plasma and RF DBD plasma, on the other hand, few studies on pattern formation have been carried out.…”
